Title: Image forming device
Inventor: FUMA HIROSHI
IPC: G03G15/14
Filed: 1989-12-11
Abstract: PURPOSE:To attain excellent paper carrying, separating and passing properties by providing an insulating film on a shielding member, securing a non-transfer region having an accurate boundary in the leading edge of a recording paper, and having a wide image part. CONSTITUTION:In a transfer unit 16 having an opening/closing shutter on an opening/closing part, a control part turns on the power source of the transfer unit 16 simultaneously when the power source of a pre-transfer paper electrifier 60 is turned on, and the shutter is released after a specified time lapses. In the transfer unit 16 a plastic film is provided on the shielding member, and the top end part of the film is abutted on the back of a transfer belt 71. Since the leading edge of the recording paper P is steadily sucked to the belt 71 even after a toner image is transferred, the non-image region of the leading edge part of the recording paper P is minimized. At this time, the non-transfer region having the accurate boundary is secured in the leading edge part of the recording paper P and it is unnecessary that a waste non-image part is enlarged. Moreover, a wide image part is obtained. An image forming device having excellent paper carrying, separating and passing properties is obtained.

Title: System for calculating relative position through inter-vehicle communications
Inventor: OKADA TAKESHI
IPC: G01S5/12
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To calculate the position of an approaching relatively to driver's own vehicle accurately by canceling the error of GSP radio wave propagation time. SOLUTION: The system comprises a transceiver 1 for inter-vehicle communication, a GPS receiving means 2, a GPS information transmitting/receiving means 3, and means 4 for calculating a relative position based on the difference of GSP radio wave propagation time. The means 4 for calculating a relative position based on the difference of GSP radio wave propagation time extracts a GPS satellite being employed commonly by an approaching vehicle and a host vehicle and determines the difference of GPS radio wave propagation time data between the approaching vehicle and the host vehicle for that GPS. When the difference of GPS radio wave propagation time is obtained for three or more GPS, the position of the approaching vehicle relative to the driver's own vehicle is determined by solving simultaneous equations having the relative position as unknown.

Title: Cylinder direct-injection type spark ignition engine
Inventor: MASUSHIRO ZENICHIROU
IPC: F01N3/20
Filed: 1990-11-28
Abstract: PURPOSE:To maintain the purifying function to almost completely eliminate the liberation of a non-treated exhaust into the atmosphere, by providing a structure of inhibiting the passing of an exhaust through a catalytic converter to cause the exhaust to flow through a bypass passage. CONSTITUTION:An exhaust passage 16 is provided with a catalytic converter 22 for purifying an exhaust. A bypass valve 38 opens or closes a bypass passage 40 directly connecting an inlet 30 and a downstream side exhaust passage portion 26 in a manner to bypass the catalytic converter 22. During generation of a fuel-cut signal, the bypass valve 38 is opened and a catalyst inlet valve 36 is closed, whereby the exhaust coming from an engine 10 passes not through the catalytic converter 22 but through the bypass passage 40, directly flowing into the downstream side exhaust passage 26. During the fuel-cut period, since the temperature of the exhaust is remarkably lowered, a catalyst (carrier) 24 is prevented from being cooled, by such bypassing of the cold exhaust. This keeps the catalyst temperature so as to enable an exhaust to be purified immediately after the next supply of fuel.
